Hi Kickstarter!

What is RA? RA is a cutting edge 3D printer controller board made by Elefu. We made the board that we wanted on our 3D printers at MakeSLC in Salt Lake City, UT. We wanted something easy to use that had the features we needed. We decided that it had to be affordable and expandable and did we ever pack it full of features. Yet we managed to keep the price low. We have worked hard to make RA and bring it to you.

Why are we using Kickstarter, when we had decided to do the
project no matter what? Three reasons:

First, our margin on this board is low, because we have
packed in so many features. We can not afford to make 5000 boards
right now. We can only afford to make what we can sell. But with Kickstarter, we can reach a lot of people quickly, and
gauge our support. If the initial run can be bigger then we can make
more boards and serve more people in the 3D printing community.

Second, because we got requests to pre-order the board. By
using Kickstarter, we get a pre-order system automatically. And,
because so many people wanted a lot of different options we can use
this to gauge what options people really want.

Third, because with Kickstarter we can have stretch goals, we
can add more features and improve the ones that are already there.
You get to tell us what is important to you and we will do it.

So please support us. Let's show everyone what a great community
exists out there for 3D printing. Spread the word! Share us on Facebook, Google+, Twitter and forums. The more people we have on board the more we can
offer. We have some great ideas for this project and with your
support we can make them reality.

Thank you. It means a lot to us to be able to do this, and with
your help we will!
